Polar ⇆ Cartesian Converter
Convert between polar and Cartesian coordinates with precision. Enter radius and angle (°/rad) to get X‑Y, or input X‑Y to get r‑θ. Perfect for CNC and trig checks.
Use degrees or radians for θ.
How θ is displayed after calculation.
Decimal places for outputs.
Choose live update or manual buttons.
Enter any two values and convert either way. θ is measured from +X, counter-clockwise.
